Answer:
y = x + c.
Step-by-step explanation:
We are given with the line y = 3x + 1 .
Now , we have to find the lines perpendicular to it .
Thus , we have to consider its slope for calculating the slope of required perpendicular lines.
Now, slope of the given line is = 3.
Let the slope of the perpendicular lines be .
Since the two lines of slope and are perpendicular = -1
Thus , = .
So, all lines having the slope are perpendicular to the given line , these lines may be represented by
y = x + c.
Answer:
B.
Step-by-step explanation:
3/12 reduces to 1/4.
1/2 alone is greater than 1/4, so when 2/10 is added to 1/2, it is certainly greater than 3/12.
Answer: B.
Answer:
The slope is 5/2 and the y intercept is -1
Step-by-step explanation:
To find the slope and the y intercept, we will write the equation in slope intercept form, y =mx+b where m is the slope and b is the y intercept
5x -2y =2
Add 2y to each side
5x-2y+2y =2 +2y
5x = 2+2y
Subtract 2 from each side
5x-2 = 2y+2-2
5x-2 =2y
Divide each side by 2
5x/2 -2/2 = 2y/2
5/2x -1 = y
y = 5/2x -1
The slope is 5/2 and the y intercept is -1
Answer:
Step-by-step explanation:
1/3x+2/3x-2/3x: x equasion
3/4+(-1/4)
1/3x + 2/4(or 1/2)
1/3x+1/2
(note that positive 2/3 and -2/3 cancel out)
